Overview
ASTM D1455-17(2023), titled Standard Test Method for 60° Specular Gloss of Emulsion Floor Polish, is an internationally recognized standard developed by ASTM International. This standard specifies the method for determining the 60° specular gloss of dried films of emulsion floor polishes after application to a substrate. By measuring the light reflected at a 60° angle from the surface, it evaluates the glossiness of emulsion floor polishes. Specular gloss is a critical appearance attribute, influencing perceptions of cleanliness and maintenance in commercial and residential flooring.
This standard is particularly useful for manufacturers, quality control laboratories, and end-users who need to compare gloss differences between floor polish products. Compliance with ASTM D1455-17(2023) helps ensure consistent, reliable results across the industry.
Key Topics
-
Specular Gloss Measurement
The standard describes how to measure the specular gloss of floor polish films using a glossmeter at a 60° incident angle. It helps identify differences in gloss between products.
-
Applicability and Limitations
While effective for most emulsion floor polishes, this method may not clearly differentiate between extremely high or low gloss finishes. In such cases, an alternative 20° angle measurement (following ASTM D523) can provide better detail.
-
Test Apparatus and Substrates
- Glossmeter: Must comply with ASTM D523 requirements, set for 60° reflection.
- Floor Polish Applicator: As prescribed by ASTM D1436.
- Substrates: Black glass (for most applications except hazy films) or official vinyl composition tiles (OVCT).
-
Reporting Requirements
Detailed reporting is mandated, including:
- Average gloss readings at 60° (and 20°, if used)
- Substrate types
- Application method and number of coats
- Instrument make/model and reference standards
-
Precision, Bias, and Safety
- Results should be repeatable within 2.5% on the same instrument (with black glass substrates).
- Users must establish their own appropriate safety, health, and environmental practices before conducting tests.
Applications
ASTM D1455-17(2023) is essential in various practical scenarios:
-
Floor Polish Manufacturing
Manufacturers use this standard in R&D and quality control to ensure consistent gloss levels across batches and to benchmark new formulations.
-
Comparative Product Testing
Distributors and commercial procurement teams apply the method to compare different products for selection and specification purposes.
-
Facility Maintenance Evaluation
Building managers and cleaning service providers use gloss measurements to assess floor maintenance regimes and verify polish performance after application.
-
Compliance and Certification
Ensures alignment with industry best practices, contributing to acceptance in regulatory or contractually mandated testing protocols.
